In an example, the present invention provides a system and method for monitoring human activity. The system has a stand alone housing, which has a processing platform, an artificial intelligence module, and a plurality of sensing devices, including rf sensors, audio sensors, and motion sensors, each of which communicates information to the artificial intelligence module for processing.

Various conventional techniques exist for monitoring people within a home or building environment. Such techniques include use of cameras to view a person. Other techniques include a pendant or other sensing device that is placed on the person to monitor his/her movement. Examples include Personal Emergency Response Systems (PERS) devices such as LifeAlert® and Philips® Lifeline—each of which are just panic buttons for seniors to press in case of an emergency. Unfortunately, all of these techniques have limitations. That is, each of these techniques fails to provide a reliable and high quality signal to accurately detect a fall or other life activity of the person being monitored. Many people often forget to wear the pendant or a power source for the pendant runs out. Also, elderly people do not want to look like they are old so often times, elderly people do not wear the pendant.

From the above, it is seen that techniques for identifying and monitoring a person is highly desirable.

DETAILED DESCRIPTION OF THE EXAMPLES

According to the present invention, techniques related to a method, and system, for processing UWB and FMCW signals using a plurality of antenna array are provided. In an example, the plurality of antenna array, including a receiving antenna array and a transmitting antenna array configured to capture and transmit signals in an omni-directional manner. In particular, the invention provides an apparatus using multi-core processors and artificial intelligence processes. More particularly, the invention provides a method and system for mapping elements onto a spatial location or map with a spatial region. Merely by way of examples, various applications can include daily life, and others.

FIG. 1 is a simplified diagram of a radar/wireless backscattering sensor system 100 according to an example of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims herein. In an example, the system is a wireless backscattering detection system. The system has a control line 101 coupled to a processing device. The control line is configured with a switch to trigger an initiation of a wireless signal. In an example, the system has a waveform pattern generator 103 coupled to the control line. The system has an rf transmitter 105 coupled to the waveform pattern generator. The system has transmitting and receiving antenna 107. In an example, the system has a transmitting antenna coupled to the rf transmitter and an rf receiver 105, which is coupled to an rf receiving antenna. In an example, the system has an analog front end comprising a filter 109. An analog to digital converter 111 coupled to the analog front end. The system has a signal-processing device 113 coupled to the analog to digital converter. In a preferred example, the system has an artificial intelligence module 113 coupled to the signal-processing device. The module is configured to process information associated with a backscattered signal captured from the rf receiving antenna. Further details of the present system can be found through out the specification and more particularly below.

Antenna

In an example, multiple aspects of antenna design can improve the performance of the activities of daily life (“ADL”) system. For example in scanning mode the present technique continuously looks for moving human targets (or user) to extract ADL or fall. Since these can happen anywhere in the spatial region of a home, the present system has antennas that have wide field of view. Once the human target is identified, the technique focuses signals coming only from that particular target and attenuate returns from all other targets. This can be done by first estimating location of the target from our technique using wide field of view antennas and then focusing RF energy on the specific target of interest once it has been identified. In an example, the technique can either electronically switch a different antenna that has narrow field of view or could use beam forming techniques to simultaneously transmit waves from multiple transmit antenna and control their phase such that the RF energy constructively builds around the target of interest where as it destructively cancels everywhere else. This return will be much cleaner and can boost the performance of our ADL+fall+vital sign sensors.

In another example considers the layout of the antennas itself. In an example, the technique places transmit and receive antennas in various different physical configurations (ULA, circular, square, etc.), that can help us establish the direction from which the radar signal returns, by comparing phases of the same radar signal at different receiving antennas. The configurations can play a role because different configurations enable direction of arrival measurement from different dimensions. For example, when the human target falls the vertical angle of arrival changes from top to bottom, therefore a vertical ULA is better suited to capture that information. Likewise during walking horizontal angle of arrival of the signal varies more therefore it makes sense to use horizontal ULA is more sensitive and therefor can provide additional information for our algorithm. Of course, there can be other variations, modifications, and alternatives.

RF Unit

In an example, the wireless RF unit can be either pulsed doppler radar or frequency modulated continuous wave (FMCW) or continuous wave doppler (CW). In an example, on the transmit side it will have standard RF units like VCO, PLL, among others. On the receive side it can have matched filter, LNA, mixer, and other elements. The multiple antennas can be either driven by a single transmit/receive chain by sharing it in time or have one each chain for each of the antennas.

Waveform Unit

In an example, waveform pattern generator generates control signals that define the type of radar signal that is generated by the radar RF unit. For example for FMCW, it can generate triangular wave of specific slope and period, which will linearly sweep the frequency of the RF unit according to this parameter. For a pulsed doppler radar, the technique will hold generate pulse of specific width and period, which will modulate the RF output accordingly.

Baseband Unit

In an example, the gain and filter stage filters the radar returns to remove any unwanted signals and then amplifies the remaining signal with different techniques. For example, the present artificial intelligence or AI technique can determine what target is desirably tracked and provide feedback to the AI technique, that will filter out radar return from any and all other signals except for the signal that is desirably tracked. If human target is moving the return signal will be fluctuating, in that case, the technique applies automatic gain control (ACC) to find the optimal gain, so that entire dynamic range of ADC in the subsequent stage is satisfied. In an example, the return signal is converted to digital samples by analog-to-digital converters (ADC), among other front-end elements.

FIG. 2 is a simplified diagram of a sensor array 200 according to an example of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims herein. Shown is a sensor array. The sensor array includes a plurality of passive sensors 201. In an example, the plurality of passive sensors are spatially disposed in spatial region of a living area. The sensor array has active sensors, such as one or more radar sensors 203. Additionally, the array has a feedback interface 205, such as a speaker for calling out to a human target in the spatial region of the living area.

In an example, the present technique is provided to identify various activities in home using non-wearable. In an example, the technique is at least privacy intrusive as possible, and will use sensors that are less intrusive. Examples of sensors can include, without limitation, a wireless backscatter (e.g., radar, WiFi.), audio (e.g., microphone array, speaker array), video (e.g., PTZ mounted, stereo), pressure mats, infrared, temperature, ultraviolet, humidity, pressure, smoke, any combination thereof, and others.

Active Sensor for RADAR

In an example, the technique can use wireless backscattering to measure motion of human, a location, and an environmental state, such as door opening/closing, or other environmental condition. In an example, the wireless backscattering can also be used to measure a vital sign, such as a heart rate and respiration rate, among others. In an example, the wireless techniques can work in non-line of sight, and is non intrusive compared to camera or microphone, or others. In an example, the technique can use radar\backscatter sensor for two purposes (1) to find the location of an action; and (2) sense different activities associated with the action. Of course, there can be other variations, modifications, and alternatives.

In an example, the present technique and system includes a radar system that operates on multiple frequency bands, such as below 10 GHz, around 24 GHz, 60 GHz, 77-81 GHz, among others. In an example, different frequency interacts differently with various objects in our environment. In an example, available signal bandwidth and permissible signal power are also regulated differently at different frequency bands. In an example, the present techniques optimally combine reflections coming from a reflector from multiple frequency bands to achieve large coverage, and/or improve accuracy. Of course, there can be other variations, modifications, and alternatives.

In an example, each radar is working at a particular frequency band will be using multiple transmit and receive antennas, as shown. In an example, using these multiple transmitters, the technique can perform transmit beam forming to concentrate radar signal on a particular target. In an example, the technique uses multiple receivers to collect reflected signals coming from various reflectors (e.g., human body, walls). After further processing this will allow us to find the direction of the reflector with respect to the radar. In an example, the technique also uses multiple transmitter and receiver to form virtual array, this will allow emulate the radar array with large element by using small number of transmitter and receiver chains. The main benefit is to improve the angle resolution without using a large array, saving space and component cost. In an example, different antenna array configurations to improve coverage (using beam forming) or add 3D localization capability (using 2-D array) are included.

In an example using standard radar signal modulation techniques, such as FMCW/UWB, on MIMO radar, the technique will first separate signals coming from different range and angle. The technique will then identify static reflectors, such as chairs, walls, or other features, from moving ones, such as human targets, pets, or the like. For moving objects that are tracked, the technique will further process signals for each of the reflectors. As an example, the technique will use different techniques to extract raw motion data (e.g., like spectrogram). In an example, the technique will apply various filtering process to extract periodic signals generated by vital signs, such as heart rate, respiration rate, among others. In an example, both the raw motion data and extracted vital signs will be passed to a downstream process, where they are combined with data from other sensors, such as radar outputs operating at different frequency or completely different sensors to extract higher insights about the environment. Of course, there can be other variations, modifications, and alternatives.

Audio Sensor

In an example, the present technique uses a sensor array that has a multiple microphone array. In an example, these microphones will be use to ascertain the direction of arrival of any audio signal in the environment. In an example, the microphone in conjunction with other sensors, such as radar, will be vital in performing two tasks: 1st it will augment radar signal to identify various activities (walking produces a different sound than sitting), if the target is watching TV it is much easier to ascertain it with audio signal; and 2nd in case of emergency like fall, the technique can use the radar signal to identify the location of the fall and then beam form microphone array towards that location, so that any audio signal produced by the target can be captured. Of course, there can be other variations, modifications, and alternatives.

Sensor Fusion and Soft Sensors

In addition to a radar sensor, which is consider as active sensors the present sensor system (e.g., box, boxes) will also have additional passive sensors that captures the sound, chemical signature, environmental conditions. Each of these of the sensors captures different context about the home that the human being tracking is living in or occupying. In an example, the UV sensor can monitor how often the sunlight comes in the room. In an example, light sensors determine a lighting condition of the human's home or living area.

In an example, a microphone array can have many functions, such as use to sense sound in the room, to figure out how long the human has spent watching TV, or how many time they went to bathroom by listening to the sound of toilet flushing or other audio signature. In an example, the present technique can use creative solutions where it can use the active sensor to find the location of the person and then tune the microphone array to enhance the sound coming from that location only, among other features. In an example, the technique can call the sensors that are derived from the hardware sensors using specific algorithms as software sensors or soft sensors. So the same hardware sensors can be used for many different applications by creating different software sensors. Here the software sensors can combine signals from one or more sensors and then apply sensor fusion and AI techniques to generate the desired output. Of course, there can be other variations, modifications, and alternatives.

Soft Sensor for Detecting Cooking and Eating Habits

In example, radar sensors can determine information about a human's location within a home, like if they are in kitchen area, or other. In an example, when the human target turns on the microphone oven, it generates specific RF signature that can be tracked. In an example, the technique can combine this information to infer if the human target walked to the kitchen and turned on the microphone. Likewise, when the human target prepares food in kitchen he/she can make lot of specific noise like utensils clattering, chopping, or other audio signature. So if a human target goes to kitchen spends sometime time in the kitchen, and the present microphone pick these sounds, the technique can infer that food is cooking or other activity.

Soft Sensor for Detecting Bathroom Habits

In an example, toileting frequency can be a very valuable indication of ones wellness. The present technique can track if a human went to the bathroom using the radar or other sensing techniques. In an example, additionally, the technique can pick sound signature of toilet flushing. In an example, the technique combines these two pieces of information, which can be correlated to toileting frequency. In an example, similarly, bathing is a unique activity that requires 4-5 minutes of specific movements. By learning those patterns, the technique can figure out ones bathing routines.

Soft Sensor for Detecting Mobile Habits

In an example, different sensors are triggered by different motion of a human target. In an example, radar can detect human fall by looking at micro doppler patterns generating by different part of the target during falls. In an example, the technique can also simultaneously hear a fall from microphone arrays and vibration sensors. In an example, the technique can also detect how pace of movement changes for an individual over a long duration by monitoring the location information provided by radar or other sensing technique. In an example, likewise, the technique can gather unstable transfers by analyzing the gait of the target. In an example, the technique can find front door loitering by analyzing the radar signal pattern. In an example, the technique can figure out immobility by analyzing the radar return. In this case, the technique can figure out the target's presence by analyzing the target's vital signs, such as respiration rate or heart rate or by keeping track of the bread crumb of the target's location trace.

In any and all of the above cases, the technique can also learn about the exact environmental condition that triggered a particular state. For example, the technique can figure out whether a human target was immobile because the target was watching TV or a video for long duration or the target was simply spending a lot of time in their bed. And these can be used to devise incentives to change the target's behavioral pattern for better living.

Soft Sensor for Detecting Vital Signs

In an example, the technique can estimate vital signs of a person by sensing the vibration of the target's body in response to the breathing or heart beat, each of the actions results in tiny phase change in the radar return signals, which can be detected. In an example, the technique will use several signal processing techniques to extract them. Of course, there can be other variations, modifications, and alternatives.

In an example, different frequency radio wave interact with environment differently. Also phase change due to vital signs (HR,RR) differs by frequency, for example phase change for a 77 GHz radar is much higher than for a 10 GHz radar. Thus 77 GHz is more appropriate for estimating heart-beat more accurately. But higher frequency typically attenuates much more rapidly with distance. Therefore, lower frequency radar can have much larger range. By using multi-frequency radar in the present technique can perform these vital trade-offs.

Soft Sensor for Detecting Sleeping Habits

In an example, the present radar sensors can detect motions that are generated during sleep, such as tossing and turning. In an example, radar sensors can also sense vital signs like respiration rate and heart rate as described earlier. In an example, now combining the pattern of toss and turn and different breathing and heart beat pattern, the technique can effectively monitor the target's sleep. Additionally, the technique can now combine results from passive sensors, such as a thermometer, UV, photo diode, among others, to find correlation between certain sleep pattern and the environmental conditions. In an example, the technique can also use the sleep monitor soft sensor to learn about day/night reversal of sleep, and the associated environmental condition by looking at different passive sensors. In an example, the techniques can be valuable in providing feedback to improve the human target's sleep. For example, the technique can determine or learn that certain environmental condition results in better sleep and prescribe that to improve future sleep.

Soft Sensor for Security Applications

In an example, the technique can repurpose many of the sensors described before for security applications. For a security application, the technique determines where one or more person is located, which can be detected using a presence detection sensor that is build on top of radar signals. In an example, the technique can eliminate one or many false positive triggered by traditional security systems. For example, is a window is suddenly opened by a wind the technique (and system) will look at presence of human in the vicinity before triggering the alarm. Likewise, combination of vital signs, movement patterns, among others, can be used a biometric to identify any human target. If an unknown human target is detected in the vicinity at certain time of the day, the technique can trigger an alarm or alert.

In an example, any one of the above sensing techniques can be combined, separated, or integrated. In an example, n addition to radar and audio sensors, other sensors can be provided in the sensor array. Of course, there can be other variations, modifications, and alternatives.

FIG. 3 is a simplified diagram of a system 30) according to an example of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims herein. As shown, the system has hardware and method (e.g., algorithm), cloud computing, personalized analytics, customer engagement, and an API to various partners, such as police, medical, and others. Further details of the present system can be found throughout the present specification and more particularly below.

FIG. 4 is a detailed diagram 400 of hardware apparatus according to an example of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims herein. As shown, the hardware units include at least a hub device 401, node 403, and mobile node 405, each of which will be described in more detail below.

In an example, the hub includes various sensing devices. The sensing devices, include, among others, a radar, a WiFi, a Bluetooth, a Zigbee sniffer, a microphone and speakers, a smoke detector, a temperature detector, a humidity detector, a UV detector, a pressure detector. MEMS (e.g., accelerometer, gyroscope, and compass), a UWB sensors (for finding locations of all the deployed elements relative to each other), among others. In an example, the hub is a gateway to internet via WiFi, GSM, Ethernet, landline, or other technique. The hub also connects to other units (Mini Node/Mobile Node) via Bluetooth, WiFi, Zigbee, UWB and coordinates them with each other. In an example, certain data processing, such as noise removal, feature extraction to reduce amount of data uploaded to cloud is included. In an example, the hub alone can be sufficient to cover a small living space. In an example, the hub is deployed as a single device somewhere in a desirable location (e.g., middle of the living space) so that it has good connectivity to all other units. An example of such deployment is provided in the Figure below.

FIG. 5 is a simplified diagram 500 of a hub in a spatial region according to an example of the present invention. This diagram is merely an example, which should not unduly limit the scope of the claims herein. As shown, the hub is deployed in the middle of the living space in a house.

In an example, as shown in FIG. 6, the system 600 has sensors, which is a subset of sensors in the hub. The sensors are configured to in various spatial locations to improve coverage area and improve accuracy for detection of critical events (e.g., fall, someone calling for help). The sensors also communicate with the hub via WiFi, Bluetooth. ZigBee or UWB, or other technique. Additionally, the sensors or each mini node is deployed in a bathrooms, where chances of fall is high, a kitchen, where we can learn about eating habits by listening to sounds, RF waves, vibrations, or a perimeter of the living space, that will allow us to learn approximate map of the space under consideration, among other locations. Additionally, each of the mini nodes can save power and costs by adding more complexity on the hub. This can even enable us to operate on battery for extended periods. For example, each of the nodes can have only single antenna WiFi and hub could have multiple antennas, for WiFi based sensing. Additionally, each of the nodes use simpler radar (e.g., single antenna doppler) vs MIMO FMCW in the HUB. Additionally, each node can be configured with a single microphone whereas the hub can have array of microphone. Of course, there can be other variations, modifications, and alternatives. As shown, each node is configured in a kitchen, shower, perimeter, or other location.

In an example, each mobile node is a subset of sensors in the hub. The mobile node sensors include a camera such as RGB or IR. In an example, each of the nodes and hub collaboratively figure out interesting events, and pass that information to the mobile node. The technique then goes to the location and probes further. In an example, the camera can be useful to visually find what is going on in the location. In an example, freewill patrolling can be use to detect anything unusual or to refine details of the map created based on perimeter nodes. In an example, onboard UWB can enable precise localization of the mobile node, which can also enable wireless tomography, where the precise RGB and wireless map of the living space is determined. As shown, the mobile node, such as a mobile phone or smart phone or other movable device, can physically move throughout the spatial location. The mobile node can also be a drone or other device.

In an example, the FMCW module outputs an FMCW signal using a transmitter, and receives back scattered signals using a receiver, such as a receiver antenna. The device has an audio module configured over the FMWC module and an inertial measurement unit (“IMU”) module configured over the FMCW module. In an example, the audio module comprises a microphone array for detecting energy in a frequency range of sound for communication and for detecting a sound energy.

An example of the processing system can be a single integrated circuit chip manufactured by Texas Instruments Incorporated sold as AM572x Sitara Arm applications processors. In a datasheet by for the Sitara Arm by Texas Instruments, “AM572x devices bring high processing performance through the maximum flexibility of a fully integrated mixed processor solution. The devices also combine programmable video processing with a highly integrated peripheral set. Cryptographic acceleration is available in every AM572x device. Programmability is provided by dual-core Arm Cortex-A15 RISC CPUs with Neon™ extension, and two TI C66x VLIW floating-point DSP cores. The Arm allows developers to keep control functions separate from other algorithms programmed on the DSPs and coprocessors, thus reducing the complexity of the system software. Additionally, TI provides a complete set of development tools for the Arm and C66x DSP, including C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a debugging interface for visibility into source code execution.”

The processing system is coupled to a energy source, including a battery and a plug connection. The system also has a graphical processing module or artificial intelligence module for performing processing functions from data received from the interfaces. An example of the processing unit is one sold under the Movidius™ brand by Intel Corporation.

In an example, Movidius provides low-power vision processing solutions, which include the Myriad 2 family of vision processing units (VPUs) plus a comprehensive Myriad Development Kit (MDK), a reference hardware EVM and optional Machine Vision Application Packages. In an example, The Myriad 2 MA2x5x family of system-on-a-chip (SoC) devices offers significant computation performance and image processing capability with a low-power footprint. The Myriad 2 lineup includes the following product configurations: MA2150: 1 Obit DDR MA2155: 1 Gbit DDR and secure boot MA2450: 4 Gbit DDR MA2455: 4 Gbit DDR and secure boot.

In an example, the Myriad 2 VPUs offer TeraFLOPS (trillions of floating-point operations per second) of performance within a nominal 1 Watt power envelope. The Myriad 2 architecture includes enough performance to support multiple cameras with flexible image signal processing pipelines for each camera, and software programmable vision processing with fixed- and floating-point datatypes supported. A robust overall dataflow design ensures mitigation of processing bottlenecks.

In an example, Myriad 2 MA2x5x incorporates an innovative approach to combine image signal processing with vision processing. A set of imaging/vision hardware accelerators supports a world-class ISP pipeline without any roundtrips to memory; at the same time they are repurposed to accelerate developers' vision processing algorithms in conjunction with a set of special purpose VLIW vision processor cores. All processing elements are tied together with a multi-ported memory that enables implementation of demanding applications with high efficiency. Further details can be found in a datasheet for Myriad 2 by Intel Corporation, and a simplified block diagram is shown in FIG. 22.

In an example, the artificial intelligence module can process data or information by a variety of artificial intelligence techniques. As an example, machine learning uses on one or more computer algorithms that improve automatically through experience. In an example, the technique can use unsupervised learning to find patterns in a stream of input, without requiring a human to label the inputs first. Alternatively, the technique can use supervised learning that includes both classification and numerical regression, which requires a human to label the input data first. Classification is used to determine what category something belongs in, after seeing a number of examples of things from several categories. Regression is the attempt to produce a function that describes the relationship between inputs and outputs and predicts how the outputs should change as the inputs change. Both classifiers and regression learners can be viewed as “function approximators” trying to learn an unknown (possibly implicit) function; for example, a status classifier can be viewed as learning a function that maps signals from a living room, for example, to one or more categories such as normal, danger, or other status.

In an example, the artificial intelligence module can provide for machine to interpret data (from any one of the data sources) in a manner that is similar to the way humans use their senses to relate to the world around them. In an example, the artificial intelligence module takes in and responds to their environment via each of the sensing modules, such as radio frequency module, audio module, inertial motion module, and others. In an example, the artificial intelligence module can also include computer vision, machine hearing, and machine touch. Other examples of artificial intelligence techniques can include, among others, natural language processing, deep machine learning, variations thereof, and combinations, and the like. Of course, there can be other variations, modifications, and alternatives. See, for example. Wikipedia.com, artificial intelligence.

In an example, the apparatus has an audio module, as represented by circularly shaped substrate member. The audio module has a microphone array comprising seven microphones, including six peripheral microphones and one center microphone configured and arranged in circular array, although there can be other configurations, quantities, and spatial layouts of the microphones. In an example, each of the microphones is electrically connect to a dual four (4) channel analog to digital converter (ADC) with 103 db of signal to noise ratio, or other suitable designs.

In an example, the analog to digital converter uses a bus to connect to a processing system, including a processing device, a signal processor, and other elements. In an example, the ADC uses an 12S interface. In an example, the 12S interface has been developed by Philips Semiconductor (known today as NXP Semiconductors). In an example, the interface uses a push pull data signal, width of one data line (SI))+2 clock lines (SCK, WS), and a serial protocol. In an example as defined in Wikipcdia.com, the “I²S” (Inter-IC Sound), pronounced eye-squared-ess, is an electrical serial bus interface standard used for connecting digital audio devices together. In an example, I2S communicates pulse coded modulation (“PCM”) audio data between integrated circuits in an electronic device. In an example, the PS bus separates clock and serial data signals, resulting in simpler receivers than those required for asynchronous communications systems that need to recover the clock from the data stream.

In an example, the processing system has a digital signal processing (DSP) core, which receives digital audio and performs a beam-forming operation, including deploying an adaptive spectral noise reduction process and the multiple source selection (MSS) process to enhance the audio quality. In an example, the processing devices, including micro-processing unit and audio signal processing unit are provided in a separate compute module, or other hardware device.

In an example, the multiple source selection processes inputs audio information from the plurality of microphones, each of which is sensing an audio signal from a spatial region, in the array directly to the DSP core, without transferring such data into the processing device, for faster detection and selection of at least one of the microphone devices in the array that has the highest audio signal therefrom. Once the microphone has been selected, the audio information from the selected microphone is outputted or further processed using the processing system. In an example, the multiple source selection processes achieves at least a few milliseconds of time off standard processing times, which often run through the processor, where the audio information traverses through the processing device. As shown, audio signals are captured from surroundings, converted to digital signals via A/D converter, transmitted to the digital processing device for audio processing, without traversing the signals through the ARM micro-processing unit core, as shown.

In an example, the ADC for the audio module has a dedicated 12S channel that is also interfaced to drive an audio amplifier coupled to a speaker. In an example, multiple speakers such as dual speakers are integrated into the apparatus. In an example, the audio amplifier can be one listed under part number TPA3126D2DAD manufactured by Texas Instruments Incorporated, among others. In an example, the driver can be a 50-W, stereo, low-idle-current Class-D amplifier in a thermally enhanced package. In an example, the driver has a hybrid modulation scheme, which dynamically reduces idle current at low power levels to extend the battery life of portable audio systems (e.g., Bluetooth speakers, and others). In an example, the Class-D amplifier integrates full protection features including short circuit, thermal shutdown, overvoltage, under voltage, and DC speaker protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions. Other features can also be included.

In an example, the audio module can also include other sensing devices. As an example, the audio module includes an inertial measurement device, a pressure sensor, a gas sensor, and a plurality of LED devices, each of which is coupled to an LED driver. Each of the devices is coupled to auxiliary control hardware, which communicates to a micro-processing unit core using a bus, such as the I2C bus, but can be others.

The ADC is a low-cost easy-to-use reference design for applications that require clear-spoken audio, such as voice triggering and speech recognition. The ADC design uses a microphone array to capture a voice signal, and converts it to a digital stream that can be used by DSP systems to extract clear audio from noisy environments. Microphone arrays 4-6 are coupled to slave ADC device, which is coupled to the master ADC device. In an example, digital audio outputs are included and feed digital audio signals into a bus, such as the I2S interface, among others. The I2S interface couples to a computing system, which includes audio output to an audio driver, and speakers.

Of course, there are other variations, modifications, and alternatives.

In an example, the present invention provides a method of capturing information from a spatial region to monitor human activities. In an example, the method includes using an apparatus comprising a housing within a spatial region of a living quarter. In an example, the method includes sensing a plurality of audio signals comprising an audio event from each of the plurality of microphone devices. In an example, each of the plurality of microphone device receives an audio signal of a different signal strength based upon a spatial location of each of the microphone devices. The method includes converting each of the audio signals from each of the microphone devices into a plurality of digital signals in a first format and processing the digital signals in the first format to a second format. The method includes transferring the digital signals in the second format using a dedicated interface device from each of the plurality of microphone devices into a receive interface device coupled to the signal processing device without transferring the digital signals in the second format to the micro processing device. The method includes processing information associated with the digital signals using the signal processing device to select one of the microphone devices that has a strongest audio signal as compared to any of the other microphone devices and transferring information associated with the digital signals from the selected microphone device to an outgoing interface device. The method includes processing the information using an artificial intelligence module to classify the information into one of a plurality of classifications. Additionally, the method includes processing the digital signals from the selected microphone device and using the artificial intelligence module to identify the event from one of the plurality of classifications.

In an example, the technique transfers learned information and activity information to third parties. The technique teaches itself to learn high level behavior that are indicative of a persons welfare using artificial intelligence techniques. In an example, the present technique will then generate summary of such activities and send it out to the human's loved ones, caretaker or even emergency response team depending on the urgency of the situation. For example for regular days, the technique can simply send short summary like “your mom had a routine activity today”, or “She was much less active today.” In an example, where the human has a care taker visiting few times a week, the technique can send a notification to them, “It seems she struggles more on yesterday”, so that the care taker can pay a visit to make sure everything is fine. Alternatively, the technique can be more acute events like fall, shortness of breathing, or others, that needs quick attention. In these scenarios, the technique can notify medical response team to provide immediate help. Of course, there can be other variations, modifications, and alternatives.

In an example, the present technique can categorize a human target with the listed ADLs, among others. Examples of ADLs including among others, bathing, brushing teeth, dressing, using toilet, eating and drinking, and sleeping. Other ADLs include preparing meals, preparing drinks, resting, housekeeping, using a telephone, taking medicine, and others. Ambulatory activities including among others walking, doing exercise (e.g., running, cycling), transitional activities (e.g., sit-to-stand, sit-to-lie, stand-to-sit, lie-to-sit in and out of bed or chair), and stationary activities (e.g., sits in sofa, stand for a while, lie in bed or sofa). Of course, there can be other variations, modifications, and alternatives.

In an alternative example, the present technique can determine activities of a human target with any one of the activities listed. The listed activities, including among others, and combinations of going out, preparing breakfast, having breakfast, preparing lunch, having lunch, preparing dinner, having dinner, washing dishes, having snack, sleeping, watching TV, studying, having a shower, toileting, having a nap, using the Internet, reading a book, shaving, brushing teeth, telephone, listening to music, doing house cleaning, having a conversation, entertain guest, among others.

In an example, the present technique can also identify a rare event. In an example, the technique identifies when a senior human falls inside a home with no one around. In an example, the technique is robust, without any false negatives. In an example, the technique uses looking at sequence of events that are before to the potential fall and after a potential fall. In an example, the technique combines the contextual information to robustly determine if a fall has occurred. Of course, there can be other variations, modifications, and alternatives.

In an example, the technique also detects and measures vital signs of each human target by continuous, non-intrusive method. In an example, the vital signs of interest include a heart rate and a respiratory rate, which can provide valuable information about the human's wellness. Additionally, the heart rate and respiratory rate can also be used to identify a particular person, if more than two target humans living in a home. Of course, there can be other variations, modifications, and alternatives.

By understanding the context of how the target human (e.g., elderly) is doing, the technique can also provide valuable feedback directly to the elderly using a voice interface. For example, the technique can sense a mood of the human based on sequence of activities and vital signs of the human and then ask, “Hi do you want me to call your son”. Based upon the feedback from the human, the technique can help connect to a third party (or loved one) if their answer is positive. Of course, there can be other alternatives, variations, and modifications.
